A nation may be said to consist of its territory, its people, and its laws. The territory is the only part which is of certain durability. “One generation passeth away and another generation cometh, but the earth abideth forever.” It is of the first importance to duly consider and estimate this ever-enduring part. That portion of the earth’s surface which is owned and inhabited by the people of the United States is well adapted to be the home of one national family, and it is not well adapted for two or more. Its vast extent and its variety of climate and productions are of advantage in this age for one people, whatever they might have been in former ages. Steam, telegraphs, and intelligence have brought these to be an advantageous combination for one united people.
In the inaugural address I briefly pointed out the total inadequacy of disunion as a remedy for the differences between the people of the two sections. I did so in language which I can not improve, and which, therefore, I beg to repeat:
One section of our country believes slavery is right and ought to be extended, while the other believes it is wrong and ought not to be extended. This is the only substantial dispute. The fugitive-slave clause of the Constitution and the law for the suppression of the foreign slave trade are each as well enforced, perhaps, as any law can ever be in a community where the moral sense of the people imperfectly supports the law itself. The great body of the people abide by the dry legal obligation in both cases, and a few break over in each. This I think, can not be perfectly cured, and it would be worse in both cases after the separation of the sections than before. The foreign slave trade, now imperfectly suppressed, would be ultimately revived without restriction in one section, while fugitive slaves, now only partially surrendered, would not be surrendered at all by the other.
Physically speaking, we can not separate. We can not remove our respective sections from each other nor build an impassable wall between them. A husband and wife may be divorced and go out of the presence and beyond the reach of each other, but the different parts of our country can not do this. They can not but remain face to face, and intercourse, either amicable or hostile, must continue between them, Is it possible, then, to make that intercourse more advantageous or more satisfactory after separation than before? Can aliens make treaties easier than friends can make laws? Can treaties be more faithfully enforced between aliens than laws can among friends? Suppose you go to war, you can not fight always; and when, after much loss on both sides and no gain on either, you cease fighting, the identical old questions, as to terms of intercourse, are again upon you.
There is no line, straight or crooked, suitable for a national boundary upon which to divide. Trace through, from east to west, upon the line between the free and slave country, and we shall find a little more than one-third of its length are rivers, easy to be crossed, and populated, or soon to be populated, thickly upon both sides; while nearly all its remaining length are merely surveyors’ lines, over which people may walk back and forth without any consciousness of their presence. No part of this line can be made any more difficult to pass by writing it down on paper or parchment as a national boundary. The fact of separation, if it comes, gives up on the part of the seceding section the fugitive-slave clause, along with all other constitutional obligations upon the section seceded from, while I should expect no treaty stipulation would ever be made to take its place.
But there is another difficulty. The great interior region bounded east by the Alleghanies, north by the British dominions, west by the Rocky Mountains, and south by the line along which the culture of corn and cotton meets, and which includes part of Virginia, part of Tennessee, all of Kentucky, Ohio, Indiana, Michigan, Wisconsin, Illinois, Missouri, Kansas, Iowa, Minnesota, and the Territories of Dakota, Nebraska, and part of Colorado, already has above 10,000,000 people, and will have 50,000,000 within fifty years if not prevented by any political folly or mistake. It contains more than one-third of the country owned by the United States–certainly more than 1,000,000 square miles. Once half as populous as Massachusetts already is, it would have more than 75,000,000 people. A glance at the map shows that, territorially speaking, it is the great body of the Republic. The other parts are but marginal borders to it, the magnificent region sloping west from the Rocky Mountains to the Pacific being the deepest and also the richest in undeveloped resources. In the production of provisions grains, grasses, and all which proceed from them this great interior region is naturally one of the most important in the world. Ascertain from the statistics the small proportion of the region which has as yet been brought into cultivation, and also the large and rapidly increasing amount of its products, and we shall be overwhelmed with the magnitude of the prospect presented. And yet this region has no seacoast–touches no ocean anywhere. As part of one nation, its people now find, and may forever find, their way to Europe by New York, to South America and Africa by New Orleans, and to Asia by San Francisco; but separate our common country into two nations, as designed by the present rebellion, and every man of this great interior region is thereby cut off from some one or more of these outlets, not perhaps by a physical barrier, but by embarrassing and onerous trade regulations.
And this is true, wherever a dividing or boundary line may be fixed. Place it between the now free and slave country, or place it south of Kentucky or north of Ohio, and still the truth remains that none south of it can trade to any port or place north of it, and none north of it can trade to any port or place south of it, except upon terms dictated by a government foreign to them. These outlets, east, west, and south, are indispensable to the well-being of the people inhabiting and to inhabit this vast interior region. Which of the three may be the best is no proper question. All are better than either, and all of right belong to that people and to their successors forever. True to themselves, they will not ask where a line of separation shall be, but will vow rather that there shall be no such line. Nor are the marginal regions less interested in these communications to and through them to the great outside world. They, too, and each of them, must have access to this Egypt of the West without paying toll at the crossing of any national boundary.
Our national strife springs not from our permanent part; not from the land we inhabit: not from our national homestead. There is no possible severing of this but would multiply and not mitigate evils among us. In all its adaptations and aptitudes it demands union and abhors separation. In fact, it would ere long force reunion, however much of blood and treasure the separation might have cost. Our strife pertains to ourselves–to the passing generations of men–and it can without convulsion be hushed forever with the passing of one generation.
